No. HotelDruid is a standalone PHP application. It can be installed alongside WordPress on the same server and database, but it doesn't register WordPress post types — it manages its own tables.

SleekView accepts a custom table prefix or fully-qualified table names. As long as the database user has read (and optionally write) access to the HotelDruid tables, SleekView discovers the schema and renders columns automatically.

SleekView's default mode is read-only. When you enable inline edits, you choose which columns are writable. We recommend testing on a staging copy first because HotelDruid has its own constraints (e.g. availability checks) that SleekView doesn't replicate.

Yes. Each plugin or table is one view, and you can have a tabbed SleekView with HotelDruid Reservations, WooCommerce Orders, and Gravity Forms Entries side by side.

Yes. SleekView reads the live schema, so any column you've added to HotelDruid tables (or any extra fields the plugin creates) will be discovered and selectable as a SleekView column.
